What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeLate-onset atrial fibrillation (LOAF) after valve surgery for degenerative mitral valve disease often with underlying mitral valve prolapse is a known phenomenon. However, there is no similar data for postoperative rheumatic heart disease (RHD) patients. We sought to assess the incidence and predictors of LOAF during postoperative follow-up in RHD patients.
methodsThis single-center retrospective case-control study included a total of 384 RHD patients with normal sinus rhythm (NSR) who underwent rheumatic valve surgery between 1st July 2008 and 30th June 2013. Patients detected with de novo persistent atrial fibrillation (AF) after 2 months of valve surgery were diagnosed as having LOAF. Presurgical demographic and echocardiographic parameters were compared between the LOAF and NSR groups to identify risk factors for LOAF.
resultsThe incidence of de novo LOAF after rheumatic valve surgery was 9.63% at an average of 2.67 ± 1.32 years follow-up. Age ≥ 32 years [OR 2.4 (95% CI 1.2-5.1); P = 0.01] and left atrial (LA) size ≥ 51 mm [OR 5.9 (95% CI 2.8-12.4); P < 0.0001] were the most significant and independent predictors of LOAF. Moreover, significant mitral valve disease was associated with a higher risk of LOAF than significant aortic valve disease (P = 0.037). LA size ≥ 51 mm at surgery showed a fair discriminative power [AUC = 0.75; sensitivity = 68%, specificity = 70%] to identify patients at high risk for LOAF.
conclusionsLate-onset AF develops in almost a tenth of the RHD patients postoperatively following corrective valve surgery. Preoperative LA size can be used to identify patients at high risk for LOAF.
